Today we start in on the stabilator construction for the RV-12 airplane. Why a Stablator and not stabilizer? The elevator and horizontal stabilzer on the RV12 are one unit so it really is a stablator.
Step 1: Machine countersink the HS-1202 Fwd Spar for 1/8 inch rivets in the holes on both flanges as called out in Figure 1.
These holes are on both top and bottom flanges.
Step 2: Machine countersink the HS-1203 Aft Spar for 1/8 inch rivets in the holes on both of the flanges as called out in Figure 1.
Step 3: Machine countersink the HS-1202 Fwd Spar for 3/32 inch rivets in the nutplate attach rivet holes on the web as called out in Figure 1. (This figure is in Vans Aircraft's plan book)
Step 4: Machine countersink both of the HS-1211 Spar Caps for 3/32 inch rivets in the holes called out in Figure 1.
NOTE: It's not noted in the written instructions, however there are two holes refered to in figure 1 that need countersinking for 1/8 inch rivet. I'm pointing to one of them in the pictures below.
Step5: Machine countersink the HS-1213 Hinge brackets at the nutplate holes for 3/32 inch per call-out in Figure 2.
Step 6: Final-Drill #12 the HS-1213 Hinge Brackets through all of the 3/16/ inch as called out in Figure 2.
Step 7: Trim the HS-1213 Hinge Bracket to make the HS-1213A Inbd and HS-1213B Outbd Hinge Brackets by removing the material shown hatched in Figure 2.
Deburr all edge and drilled.
Step 8: Machine countersink the #40 holes in the HS-1209 Spar Cap Spacers for 3/32 inch rivets per call-out in Figure 3.
Step 9: Separate the HS-1209 Spar Cap Spacers by removing the material shown hatched in Figure 3.
Step 10: Separate the HS-1224 Doublers by removing the material shown hatched in Figure 4. Deburr the edge of the separated parts.
Note: Readied the parts for the next steps by alodining and priming. The gloves in the picture is just a reminder to wear protective gear (gloves and respirator) when working with zinc chromate primer.
